The bleBox switchBoxDC module is a device with built-in WIFI communication and several communication standards via a browser, Android application or HTTP queries, allowing you to remotely turn on and off any electrical devices in home. In this way, you can check whether, for example, you have turned off the iron or limit children's access to the TV or console, or when you leave the house, turn off the voltage on all electrical sockets in the house, making them safe. SwitchBox is controlled using a Smartphone, it can cooperate with the entire BleBox family of smart home devices, so we can also control other systems, e.g. alarm or irrigation. The great advantage of this device is the potential-free contact, which allows you to switch electrical loads at any voltage 0-230V AC and 0-30V DC, which means that it can be used for both direct and alternating current devices. The additional possibility of connecting a button allows you to also control a local switch; to avoid running wires to the button, you can also connect it wirelessly - using inBox
